Hi!!! I'm experiencing the problem with the click beat in the sound level. I've TVP 11.0.1 bought it recently and i'm using the 32 bit version. The only solution I found is to convert the sound file from wav to aiff..or vice-versa, delete the old one and re-import it..is quite annoying...i wonder if there is a way to delete the beat clicks...I forgot to mention that the click sound appear also if the stopwatch is off.

Ok, you have version 11, but if you installed the version from 2015, you are clearly not up to date. =)

Please go to Help menu in TVPaint > Check for updates.

You will be redirected to TVPaint website ; if a big blue button "dowanload" appears, you are not up to date.
Click then on that button to download the update. Then quit TVPaint before installing the update.
